Few days ago I found a very good Open Source project for sharing and synchronization (Dropbox alternative) called Pydio. Heard before for this project, but I have never tried to install it before. I tried the demo and decided to install Pydio on my own server and check this little bit more. Installation procedure went smoothly and in 5 minutes I had my sharing web site ready to use.

But, when I tried to upload multiple files, all of them larger than 3Mb, browser simply returned:

Error 500, Internal server error

1	Error 500, Internal server error

Then I checked Apache2 log, and here is what I found:

[Thu Dec 11 14:45:58 2014] [warn] [client xxx.xxx.xxx.xxx] mod_fcgid: HTTP request length 15735832 (so far) exceeds MaxRequestLen (15728640), referer: https://mynicesite.dev

1	[Thu Dec 11 14:45:58 2014] [warn] [client xxx.xxx.xxx.xxx] mod_fcgid: HTTP request length 15735832 (so far) exceeds MaxRequestLen (15728640), referer: https://mynicesite.dev

It seams that MaxRequestLen directive of mod_fccgid is too low. To fix this, you need to update few options in your php.ini file. Search for upload_max_filesize which puts limit on any single file, default value should be set to this:

upload_max_filesize = 2M

1	upload_max_filesize = 2M

change this value to whatever you want, but I strongly suggest you to set >50M. Then search for post_max_size, default value is:

post_max_size = 8Mb

1	post_max_size = 8Mb

this is the size of the entire body of the request, which could include multiple files. Set this value at lest 2-3x as upload_max_filesize. Continue reading Apache2 – mod_fcgid: HTTP request length exceeds MaxRequestLen

Today I got strange error on my production server when I tried to enable SSL on three domains. Since I use ISPConfig as hosting control panel I assumed it will work without problems. But I was wrong. I did little bit of research on this topic, and I found a simple solution.

If you look at /etc/apache2/ports.conf file, you will see:

NameVirtualHost *:80
Listen 80

1 2	NameVirtualHost *:80 Listen 80

This way Apache knows which virtual host to serve based on the different host names. And it works fine for *:80 port. But, for 443 port it’s disabled, so you need to update ports.conf as follows to make it work:

<IfModule mod_ssl.c>
NameVirtualHost *:443
Listen 443
</IfModule>

NameVirtualHost *:443

Listen 443

</IfModule>

Make sure to restart Apache and it will work fine.

I hope this tip will save you some time.
